Working on an OBEL guitar. Everything works except the tone pot. And the tone overall seems to be a little muddy, so something is not quite right..

In looking things over the only wiring mistake I make (I think ) is perhaps using the opposite outside lug of the volume pot for input/ground.

IOW, typically in say a standard tele diagram, the volume pot lug closest to the pickups is used for input and the one farther is for ground. I think I did the opposite.

Does this matter to anything? Maybe it has something to do with my issue, maybe not.....

When you connect a potentiometer, it really doesn't matter which of the outer lugs you solder to other than the fact it will change the direction in which the resistance increases/decreases as you rotate it. In other words, if you connect it backwards, you'll have full resistance at 0 on your knob instead of no resistance.

Based on what you've described, it sounds more like you have either a grounding issue or could have possibly cooked the capacitor while soldering it in. If you overheat the capacitor, it can completely change the performance characteristics of it.
